What is the new crown vaccine ?
Domestic new crown vaccine belongs to the inactivated vaccine , which is a very mature vaccine technical route. During the preparation process, the virus has been treated to "death" and has lost its ability to reproduce and infect. Usually, after 14 to 28 days of the first shot, the antibody positive rate can reach about 60%-90%. Vaccination with the second shot again can effectively improve the antibody positive rate. The vaccine is generally composed of the entire virus or bacteria, or it may be composed of its lysed fragments. The production of
latch vaccine is mainly to further purify microorganism until the vaccine only contains the required antigen components. The previous application data of
confirmed that it does not reach 100% immune protection. Therefore, in addition to vaccination, other immunization measures should also be paid attention to, including wearing masks, avoiding close contact with infected people, and maintaining regular disinfection of the environment. These are important measures to prevent diseases.
Will I really suffer from lung nodules after receiving the Sinovac vaccine? The Internet rumor that lung nodules appeared after receiving the Sinovac COVID-19 vaccine" has become a hot search, causing uneasiness among many people. Many industry experts have issued popular science interpretations on such false information.
The detection rate of lung nodules in recent years has been relatively high. From the perspective of immuno principle, the risk of inactivated vaccines and lung nodules is not related. The reason why the detection rate of lung nodules is relatively high is because of the improvement of instruments and equipment. High, Sinovac COVID-19 vaccine is an inactivated vaccine, which is a very mature vaccine technology route. During the preparation process, the virus has been treated to "death" and has lost its ability to reproduce and infect, and will not infect lung tissues to produce nodules .
In short, the increase in detection of lung nodules has little to do with the new crown vaccine. We cannot ignore the important role of the new crown vaccine in fighting the epidemic because of some rumors. ht What causes ml3
lung nodules?
pulmonary tuberculosis : phospholipids are present in the cell wall of Mycobacterium tuberculosis in the binding form, which can promote monocyte hyperplasia and transform macrophage in the inflammatory foci into epithelial cells , shape The giant cells in the cigarette form lung nodules.
Long-term smoking: If the patient has a long history of smoking, nicotine in cigarettes will cause serious damage and pollution to the lungs. When smoke and dust gather in large quantities in the lungs, lung nodules can be caused.
infection: If the patient's immune function decreases, he is infected by various pathogens such as bacteria, viruses, Mycoplasma , Chlamydia , parasites, etc., causing damage to lung tissues and may also cause lung nodules, which are mostly benign lesions.
1 Air pollution: Lungs filter fragrance every day In addition to smoke, the filtering is at most dust and tiny particles in the air. At present, air pollution is relatively serious. Some areas are prone to smog weather. Due to environmental pollution, a large amount of dust and particles in the air such as PM2.5 can be deposited in alveolar and or bronchials, and accumulate in the lungs for a long time to form lung nodules.
Family history: Some clinical investigations show that pulmonary nodules are The occurrence is related to family history. If parents or siblings have a history of malignant tumors, especially lung tumors, the patient's risk of lung nodules increases.
How to prevent lung nodules?
First: Regular physical examination
long-term exposure to irritating dust or flour and other substances For a qualitative human body, regular physical examinations should be performed so that doctors can promptly detect lesions in the lung tissue.
Second: Ensure a good living environment
For example, some fume will be generated when cooking at home. You can use a range hood to avoid inhaling too much fume. Be careful to open the windows frequently to ventilate to avoid inhaling irritating air and dust.
3: Important factors in chronic lung nodules
You must pay more attention to this issue in normal times. If you suffer from chronic infectious diseases of
, you should go to the hospital for treatment in time to prevent the condition from worsening and developing into pulmonary nodules.
Fourth: Regular sports
Especially aerobic exercise, such as jogging, brisk walking, swimming, etc., is a very effective measure to prevent various tumors. This is also a cancer prevention measure that we have drawn definite conclusions through large-scale clinical population surveys.
